Keep the bilge area clean and free from debris that could clog ports or inhibit float movement. Also, keep the
battery (starboard) that provides power to the bilge pump charged. If the battery is not charged and flooding
occurs, the boat could swamp causing damage and possible loss of life or property.
Raw Water Washdown Pump
The washdown pump is
mounted on top of the starboard aft stringer and is
equipped with a pressure switch. This pump shares the same seacock with
the baitwell pump and is accessible via the bilge hatch.
Before operating the washdown pump, make sure that the seacock at the
baitwell pump is in the open position before turning on the pump. The
seacock is wide open when the seacock lever is in the vertical position.
When the seacock lever is in the horizontal position, the seacock is closed.
The seacock should remain closed when the baitwell and/or washdown
pumps are not in use.
To turn on the washdown pump, locate the washdown switch on the instrument
panel and press the switch to the forward position. If you turn on the washdown
pump switch and you do not feel pressure, the seacock may not be open. Verify
that the seacock is open and depress the switch again.
The raw water washdown fitting is located in the port aft corner of the aft cockpit.
Just attach a standard variety garden hose to the fitting.
When the washdown pump is on, turn the control knob on the fitting to verify that
the washdown system is working properly. When not in use, the washdown switch
should be left in the off (down or aft) position.
Fish Boxes with Macerator Pump
Your boat is equipped with 2 aft fish boxes with a combined capacity of 130 gallons. The fish boxes are installed
below the floor hatches located just forward of the transom.
The fish box macerator pump is installed in the bilge as far aft as possible and is equipped with an automatic float
switch. This pump drains the aft fish boxes and/or macerates any fish particles. As the fish boxes drain, water
and/or debris travel to the collector box attached to the pump and then to the fish box macerator pump which
pumps the water and/or debris overboard.
The fish box macerator pump operates on 2-way rocker switch
(labeled Fish Box Pump) that is located on the switch panel. To
properly operate the fish box macerator pump, fill either of the aft
fish boxes with water. Then depress the fish box pump switch to
the forward position. The water and fish particles will be pumped
out of the tubs and then overboard via a fish box thru hull on the
side of the boat. When you are finished emptying the fish box,
place the fish box switch in the aft position to turn off the fish box
macerator pump.
Fish box pump
& collector box
Note: The casting deck storage boxes double as the forward fish boxes. Any water that collects
in these storage boxes will gravity drain overboard via thru hulls. These storage boxes are not
plumbed to the fish box macerator pump.
To check the system for drainage, remove the white 90-degree elbow fitting that connects the hose to the holding
tank. The fitting is held in place with a rubber grommet therefore no hose clamps need to be removed. After
removing the fitting, feel around just inside the holding tank for the 2 round plastic buttons (approx. ½” in
diameter) and simply lift the 2 buttons to check the operation. If the float is working properly, the pump will
activate. On occasion, you may find excessive debris in the holding tank that is causing a blockage. Just remove
the debris through this same opening. When you are finished checking the operation, reinsert the 90-degree
elbow fitting back into the rubber grommet until is seats itself.
